T0 all whom t may concern;

Be it known that I, ANDREW J. Nigeria, a citizen of the United States, residing at Boonton, in the county of Morris and State of New Jersey, have invented a certain new and useful Improvement in Rail-Joints, of which the following is it Specification.

The invention relates to insulated joints for supporting and connecting the abutting ends of railway rails, and the object of the invention is to provide a joint of simple and economical construction, easily assembled and installed, by which the rail-.ends shall be strongly joined, and reliably insulated from each other.

The invention consists in certain novel features of construetion and arrangement of parte. by which. the above objects are attained, t0 he hereinafter described- The accompanying drawings forni a part 0f this sneeaten, and. Show preferred forms of the invention as it has been carried out in practice.

Figure l is a plan view of the improved joint. Fig. 2 is a corresponding side view. Fig. 3 is a vertical longitudinal section, partly in elevation, taken on the line 3-3 in Fig. 4, and Fig. 4 is a transverse section partly in elevation, taken on the broken line 4--4 in Fig. l. 5 is a plan View of the base-plate for the joint; Fig. 6 is a plan View of a shim or filling-.piece therefor, and Fig. 7 is an edge view of the shim. Fig. S is a central longitudinal vertical Section through the base-plate, on the line 8-8 in Fig. 5. Fig. 9 is a plan view of a modified form of the base-plate, and Fig. 10 is an edge view thereof. Fig. 11 is an edge view of a shim to be used with such modified base-plate. Fig. 12 is an end elevation of an insulating bushing, and Fig. 13 is a corresponding diametrical section.

Similar letters of reference indicate like parts in all the figures.

A and B are abutting rail-ends, shown as of standard type with the usual base-lianges A1, B1, and C is a base-plate, preferably of steel, of suliicient length to underlie and support the rail-ends, and adapted to be fastened to a tie, not shown, by lag-screws D or other fastening means extending through holes c1 in the side margins of the plate. At one end of the plate is a shallow depression or recess c of a width a little greater than the base-flange B1 of the rail B and extending' a, short distance beyond the transverse center line of the plate, 0r beyond the abutting line of the rail-ends, and E is a fillingpieCe or shim, preferably of hard wood, shaped to match to and fill the recess iiush with the remaining upper face of the plate. A wooden pin El projecting downwardly from the under face of the shim is received in a hole 02 in the recess and serves to locate the shim properly and to hold it in position in the recess. Along each side margil-i of the plate C, in addition to the holes c1 for the lag-screws, is a series of holes c3 drilled and tapped to receive short stud-bolts F serving to hold the horizontal flanges G1 .of the shaped angle-plates G to the base-plate. These angle plates extend longitudinally, 0n@ Qn each side of the base-plate with their flanges G vertical and parallel with the railends.

H. H1 are Check nieces of hard Wood shaped on their inner faces to match to the adjacent side surfaces of the rail, with their outer faces plane and vertical, extending across the rail-joint and received between the rails and vertical flanges G of the angleplates.

The webs .of the rail-ends are bored thron h at c and b to receive transverse bolts 'J J which extend through the angleplates G and cheek-pieces H, H1, and by the .nuts J1 J1 thereon bind these parts together and to the abutting railends. The holes in the angle-plates are larger than required for the reception of the bolts J and receive annular bushings K of fiber or other suitable insulating material which serve to insulate the bolts from the angle-plates. The outer faces of the bushings are protected by washers K1. The recess c and the shim E therein are wider than the base of the rail B to insure aga-inst electrical contact of the rail-flange with the base-plate at the sides, and extend longitudinally beyond the end of the rail B and a short distance beneath the rail-end A to insure insulation at the extreme end of the rail. Thus constructed the rail-ends are insulated from each other and both are firmly joined and supported. The abutting ends of the rails are separated as usual by insulating end-posts L of indurated ber or other suitable material.

By providing the recess c to receive the shim, the correct position of the latter beneath the rail-end is insured, aided by the pin El in engagement with the plate, and the whole forms an eminently eiiicient joint in which the parts are securely held against accidental displacement. r

In Figs. 9, 10 and l1 a base-plate C1 is shown, of modified form, having a raised yportion C2 formed integral with the plate at one end. The remaining'central part of the plate receives a shim E2 correspondinr in thickness to the raised portion, and held in position by a pin E3 received in a hole' c4, and serving to insulate one rail-end from the plate'as before. The Vangle-plates, cheekpeces, and other'portions, not shown, for this form of the joint, may be understoodl `to be similar to those above described and to serve in the same manner. 1

Other modifications may be made in the forms and proportions of the parts as may be found necessary or desirable in adapting the invention tovarious types. of rails ory other conditions of service. i

l. In a rail-joint, a base-plate having the upper face at one end of its central longitudinal portion higher thanv the other and integral with such plate, and having a hole in the lower portion, a shim of insulating material applied upon such low portion'and extending beyond the line of abutment of the rail-ends, a pin of insulating material rigid with and extending from the lowerl face of saidshim and engaged in said hole, angle-plates securedto said base-plate at` thel side margins of the latter, insulating .cheek-pieces .between said anglerplates and,` sides of such rail-ends, bolts extending' transversely through said 4angle-plates, cheek-pieces and rail-ends,'and annular inof such rail-ends, bolts extending transversely through said' angle-plates, cheekpieces and rail-ends, and means for linsulating said bolts from Vsaid angle-plates. y

3. In a rail-joint, a base-plate having a recessV at one end extending longitudinally thereof beyond the line of abutment of the rail-ends, and having'a hole in such recess,

a shim of insulating ,material matching toand received in said recess,` a`p1n rigid .with and depending from said shim received in said', hole, angle-plates secured, to said base-plate at the side margins of the latter,

insulating cheek-pieces between said angleplates and sides of such raileends, bolts extending transversely through said angleplates, cheek-pieces and rail ends, and means for insulating'said bolts from `said angleplates.

In testimony that I claim the invention above set forth I aix myV signature, in

presence of twoV witnesses.v f
